In the above configuration, as shown in FIG. 6, the protruding length t of the connecting portion 5a of the S terminal 5 is short, and the connecting portion 5a is located in the terminal hole 4a so as to be immersed in the connecting portion 5a. On the other hand, plug 20
Therefore, it is necessary to push the plug 20 firmly into the connecting portion 5a to connect it, and the pushing force lifts the S terminal 5 in a direction to be peeled off from the support substrate 9. Therefore, the soldering for connecting the S terminal to the support substrate 9 may loosen and become loose, or the soldering may be damaged.

Conventionally, in order to solve the above-mentioned problem, the S terminal 5 is fixed to the holder plate 4 with the screw 12 so that the S terminal 5 is not peeled off from the support substrate 9. 12 is used, the number of parts increases, the cost increases, and the screw 1
It is troublesome to take time and effort for the second fixing work.

An object of the present invention is to provide an electronic apparatus that can easily attach and fix an S terminal with a simple and inexpensive structure in view of the above-described conventional drawbacks.

In order to achieve the above object, the invention according to claim 1 is characterized in that a synthetic resin holder plate is disposed in an opening portion opened in a proper position of a cabinet containing a device main body, and a terminal hole is opened in the holder plate.

The edge of the support board is engaged with the engagement piece, and the support is supported. In the electronic device in which the connection portion of the S terminal is inserted into the terminal hole by fixing the substrate to the chassis in the cabinet, and the plug is fitted to the connection portion of the S terminal. An abutting rib that faces the support substrate at an interval that is the same as or slightly larger than the height of the S terminal with a gap in between is integrally projected on the back surface of the holder plate, and the upper side of the S terminal is opposed to the abutting rib. The end face It is characterized that it has to be approached.

According to a second aspect of the present invention, in the first aspect of the present invention, a guide plate that is flush with the S terminal facing surface of the abutting rib and extends parallel to the upper end surface of the S terminal is provided on the holder plate and the abutting rib. The S terminal is slid along the guide plate so that the connecting portion of the S terminal is inserted into the terminal hole.

According to a third aspect of the present invention, there is provided a liquid crystal television in which a liquid crystal module is built in a cabinet, wherein a synthetic resin holder plate is disposed at an opening formed at an appropriate position of the cabinet, and a terminal hole is provided in the holder plate. At the same time, an engaging piece is integrally projected on the back surface of the holder plate, and an S terminal is fixed on a supporting board made of a printed wiring board, and an edge of the supporting board is engaged with the engaging piece. In addition, in the electronic device in which the connection portion of the S terminal is inserted into the terminal hole by fixing the support substrate to the chassis in the cabinet, and the plug is fitted to the connection portion of the S terminal. A contact rib that faces the support substrate at an interval that is the same as or slightly larger than the height of the S terminal with the terminal hole in between is integrally projected on the back surface of the holder plate;
A guide plate that is flush with the S terminal-facing surface of the abutment rib and extends parallel to the upper end surface of the S terminal is integrally projected on the holder plate and the abutment rib, and the S terminal is slid along the guide plate. Thus, the connection portion of the S terminal is inserted into the terminal hole, and the upper end surface of the S terminal is brought into contact with or close to the abutment rib.

According to the first aspect of the present invention, when the plug is strongly pushed into the connection portion of the S terminal and connected, the S terminal is lifted by the pushing force and pressed against the support substrate by the abutting rib. Therefore, the soldering to connect the S terminal to the support substrate is loose and loose,
The soldering is not damaged, and the fixed state of the S terminal with respect to the support substrate can be reliably maintained.

Since the abutting rib is integrally projected on the holder plate, the number of parts does not increase, and the cost can be reduced as compared with the case where a conventional S terminal fixing screw is used. Since there is no insertion hole, the external appearance of the holder plate can be maintained satisfactorily.

Further, the S terminal can be fixed at a predetermined position only by engaging the edge of the support substrate with the engagement piece and fixing the support substrate to the chassis in the cabinet. As compared with the case of using screws, the assembly work can be performed quickly and easily.

According to the second aspect of the invention, by sliding the S terminal along the guide plate, the connecting portion of the S terminal can be reliably and easily inserted into the terminal hole.

A corded plug (not shown) is also connected to the connection portion 6a of each RCA terminal 6 in the same procedure.

According to the above configuration, when the plug 20 is strongly pushed into the connection portion 5 a of the S terminal 5 and connected, the S terminal 5 is lifted by the pushing force and is about to be peeled off from the support substrate 9 by the contact rib 22. Therefore, the soldering for connecting the S terminal 5 to the support substrate 9 is not loosened and loosened, and the soldering is not damaged, and the fixed state of the S terminal 5 to the support substrate 9 is reliably maintained. Can do.

Since the abutting rib 22 is integrally projected from the holder plate 4, the number of parts does not increase, and the cost can be reduced compared to the case where the conventional S terminal fastening screw 12 (see FIG. 6) is used. Moreover, since there is no screw insertion hole 13 (refer FIG. 6) in the holder plate 4, the external appearance of the holder plate 4 can be maintained favorable.

Furthermore, the S terminal 5 can be fixed at a predetermined position only by engaging the edge of the support substrate 9 with the engagement pieces 10 and 11 and fixing the support substrate 9 to the chassis 15 in the cabinet 2. As compared with the case where the conventional S terminal fastening screw 12 (see FIG. 6) is used, the assembly work can be performed quickly and easily.

Moreover, by sliding the S terminal 5 along the guide plate 23, the connecting portion 5a of the S terminal 5 can be reliably and easily inserted into the terminal hole 4a.
